Who has broken cam caps?

I've read a few places of a few people breaking these. I know MMR makes upgraded billet caps, but I'm curious who has broken their stock ones? I feel like if they were as common to break as say OPG's or timing chains, you'd hear more about it.

Having a set of heads ported, wondering if there is value while they're at the shop to have the caps installed or if money is better spent elsewhere?

I’ve not really heard of this being a regular weak point.

It's only necessary if you were going to do an aggressively lobed cam set up that requires extremely high spring pressure. Over time, the cast aluminum cap can start to lift as it's ultimately a pretty soft piece. If you're going for a max effort coyote, it's a must.
